3.1 CPU, Memory and Chipset
3.1.1 CPU
The Intel® Xeon® processor E5-2658/E5-2648L implements several key technologies:
‹
Four channel Integrated Memory Controller supporting DDR3
‹ Integrated I/O with up to 40 lanes for PCI Express Generation 3.0
‹ Two point-to-point link interface based on Intel® QuickPath Interconnect (Intel® QPI) up
to 8.0GT/s
‹ 20 MB of shared cache
‹ Streaming SIMD Extensions 2 (SSE2), Streaming SIMD Extensions 3 (SSE3) and
Streaming SIMD Extensions 4 (SSE4)
The Intel® Xeon® processor E5-2658/E5-2648L supports several advanced technologies:
‹
Execute Disable Bit
‹ Intel® 64 Technology
‹ Enhanced Intel® SpeedStep® Technology
‹ Intel® Virtualization Technology (Intel® VT)
‹ Intel® Hyper-Threading Technology (Intel® HT Technology)
The Intel® Xeon® processor E5-2658/E5-2648L has a maximum TDP of 95W/70W and has
an elevated case temperature specification. The elevated case temperatures are intended to
meet the short-term thermal profile requirements of NEBS Level 3. The Intel® Xeon®
processor E5-2658/E5-2648L is ideal for thermally constrained form factors in embedded
servers, communications and storage markets.
